China Imposes Consumption Tax on Vanadium Flow Batteries

Starting September 1, China has introduced a 2% consumption tax on vanadium flow batteries, which is scheduled to increase to 4% by next September. This new fiscal policy is expected to compress the internal rate of return for energy storage projects, adding financial pressure to an already complex market landscape. Concurrently, long-duration energy storage systems with a duration of four hours or more have been officially incorporated into the national Power Law, granting them an independent legal identity and signaling long-term state support.

Market Reality Versus Planned Capacity

Despite the legislative backing, the actual deployment of vanadium flow batteries reveals a significant gap between ambition and reality. Between 2024 and 2025, the sector saw over 5 billion RMB in financing, and 2025 witnessed 51 new production projects with a planned capacity of 24GW and 96.6GWh. However, from January to July 2026, actual commissioned capacity reached only 186.94MW, with merely three new projects breaking ground, marking a substantial year-on-year decline.

Industry Cash Flow Challenges

While financing exceeded 5 billion RMB recently, actual deployed capacity in early 2026 reveals a stark contrast to ambitious plans, forcing companies to rely on selling test stacks and electrolyte to maintain cash flow.

Furthermore, industry insiders note that many companies are currently surviving by selling test stacks and electrolyte to maintain basic cash flow, rather than relying on large-scale project revenues. This transitional phase underscores the necessity for targeted subsidies or tax exemptions to bridge the gap until economies of scale are fully realized.

This discrepancy highlights the commercialization bottlenecks facing the industry. While the technology is proven and legally recognized, the high upfront costs, exacerbated by the new consumption tax, require further supply chain optimization and innovative business models to achieve widespread grid-scale adoption in the Chinese market.
